Which of the following statements is true about the kinetic molecular theory?
A) The volume of a gas particle is considered to be small: about 0.10 mL.
B) Pressure is due to the collisions of the gas particles with the walls of the container.
C) Gas particles repel each other but do not attract one another.
D) Adding an ideal gas to a closed container will cause an increase in temperature.
E) At least two of these statements are correct.

According to the kinetic molecular theory, pressure in a gas is a result of the collisions of gas particles with the walls of the container. The volume of a gas particle is considered negligible compared to the volume of the container, so statement A is not correct. Gas particles do not necessarily repel each other; some gases, such as hydrogen, actually attract each other under certain conditions. Statement C is not universally true. Adding an ideal gas to a closed container can lead to different outcomes depending on the conditions, but it will not always cause an increase in temperature. Statement D is not correct. Therefore, only statement B is true.
